When the hand is relaxed, the weapon is deactivated, and the blades retract into the body of the weapon (sheath) protecting the user, so the weapon may be safely carried in the user's pocket or purse. ## Claims ### Claim 1 A protective weapon configured to transition from a deactivated state to an activated state, the protective weapon comprising: a housing portion including: a rigid upper member; a rigid lower member; and an elastic sheath extending between the rigid upper member and the rigid lower member; and a plurality of blunt blades fixedly attached to the rigid lower member, the plurality of blunt blades including a first blade, the first blade disposed substantially within the housing portion when the protective weapon is in the deactivated state, each blade of the plurality of blunt blades having: a blunt body portion; an upper portion joined to the blunt body portion and having a pointed tip; and a forward-facing concave surface adjacent to the pointed tip, wherein the protective weapon is configured to transition from the deactivated state to the activated state when a compressive force is applied to bring the rigid upper member and the rigid lower member into closer proximity. ### Claim 2 (depends on 1) The protective weapon of claim 1, wherein the rigid upper member further includes a first slot and a second slot, and the first slot and the second slot are spaced apart by approximately a width corresponding to a width of an average human finger. ### Claim 3 (depends on 2) The protective weapon of claim 2, wherein the plurality of blunt blades includes a second blade; the first blade is aligned with the first slot; and the second blade is aligned with the second slot. ### Claim 4 (depends on 1) The protective weapon of claim 1, wherein the elastic sheath is configured to decrease from a first height to a second height when the compressive force is applied. ### Claim 5 (depends on 4) The protective weapon of claim 4, wherein the elastic sheath is configured to return to the first height when the compressive force is removed. ### Claim 6 (depends on 1) The protective weapon of claim 1, wherein the outermost pointed tip of the first blade is disposed outside of the housing portion when the protective weapon is in the activated state. ### Claim 7 (depends on 1) The protective weapon of claim 1, wherein the blunt body portion includes a substantially rectangular cross section along a horizontal plane. ### Claim 8 (depends on 7) The protective weapon of claim 7, wherein the upper portion includes a substantially triangular cross-sectional shape along the horizontal plane. ### Claim 9 (depends on 1) The protective weapon of claim 1, wherein the protective weapon is sized and dimensioned to correlate with an average size of a human palm. ### Claim 10 (depends on 1) The protective weapon of claim 1, wherein a lower end of the first blade is disposed within a receptacle extending from the rigid lower member. ### Claim 11 A method of manufacturing a protective weapon, the method comprising: molding an upper rigid member and a lower rigid member from a hardenable plastic; forming a first slot in the upper rigid member; fixedly joining a lower portion of a first blunt blade to the rigid lower member, the first blunt blade having the lower portion and an upper portion having a pointed tip and a forward-facing concave surface adjacent to the pointed tip; inserting the first blunt blade into a substantially hollow housing portion through a first opening of the housing portion; securing a first end of the housing portion associated with the first opening to the lower rigid member; and securing a second end associated with a second opening of the housing portion to the upper rigid member, such that the housing portion interconnects the upper rigid member and the lower rigid member. ### Claim 12 (depends on 11) The method of claim 11, further comprising aligning an outermost the tip portion of the first blunt blade with the first slot. ### Claim 13 (depends on 11) The method of claim 11, wherein the first end of the housing portion is secured to the lower rigid member via epoxy. ### Claim 14 (depends on 11) The method of claim 11, wherein the housing portion includes a flexible compressible material. ### Claim 15 (depends on 11) The method of claim 11, further comprising joining a lower portion of a second blunt blade to the lower rigid member. ### Claim 16 (depends on 15) The method of claim 15, further comprising inserting the second blunt blade into the first opening of the housing portion. ### Claim 17 (depends on 16) The method of claim 16, wherein the first blade and the second blade are substantially parallel to one another. ### Claim 18 (depends on 11) The method of claim 11, wherein the housing portion is configured to be compressed by a hand squeezing the upper rigid member and the lower rigid member together. ### Claim 19 (depends on 18) The method of claim 18, wherein the housing portion is configured to allow the pointed tip of the first blunt blade to protrude from the upper rigid member when the housing portion is compressed.
